Application May 12, 1947, SBl'ialNO, 747,474 3 Claims. (o1.24 159) The present invention relates to safety pins of the type having. a pair of. guard bars with a coacting pin proper disposed therebetween, the pin proper being aiflxed tonne of the ends of each of said. guard bars, with the. free sharp end of.

the pin proper engageablev by the free ends ofthe guard bars when the safety pin is in a closed condition. The. principal. object of the present invention is the. provision of the. pin proper, in the safety pinaboveindicated, which may be in a spaced relation from the plane of said guard bars, inorder that the pin proper may pierce and engage fabric material ofsconsiderable thickness.

.A still further object of the present invention is theprovision in. a safety pinv of. the type indicated, of a. pin proper which normally is capable of flexing by. its free end towards thefree ends of said guard bars to be engaged. by the latter inv order that. the safety pinv may. remain closed.

A still further object of. the present invention is to generally improve .the construction of a safety pin of the typeabove indicated.

With. the .above general objects in view and others that will appear as the invention is better understood, the same consists in the novel construction-combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended. claims.

Inthe drawing forming a part of this application:

Fig. 1' is a top elevational view of the safety pin while in a closed position;

Fig. 2 is a sideelevational view thereof while in a. closed position;

Fig. 3 is a top elevational view thereof while in an open position;

Fig. 4 is an end elevational view of the safety pin while in a closed position;

Fig. 5 is a similar view of the safety pin while in an open position; and

Fig. 6 is a fragmentary view, partly in elevation;

and partly in section, the view having been taken on line 6-6 of Fig. 3.

Referring in detail to the present drawing, there bent-toward the longitudinal axial center of the safety. pin andaway from the plane of said guard bars. I 0, for effecting arm l2. Thus, the two arms ii. in the. two guard bars H) are in a raised positionwith relation to theplaneof said guard bars [0, for the purpose. which will be later apparent.

Each of said arms I2 is formed into hook IS. The. two hooks l3 areeffected by the right hand twist of. the free ends of arms l2, with the free ends of saidhooks lBflattenedtoeffect tongues I4.

From the hereinabove construction it will be seen that the free ends of said hooks l3 are-disposed by their. tongues. I tinto opposite directions, by virtue of which construction hooks 13 with tongues. M. shift away from each other when manualv pressure is imparted to said guard bars [0 for flexing the latter towards each other, as'is clearly seen in Figs. 3 and 5.

Pin proper It. includes leg portion. I6 which is substantially in a. perpendicular relation with the body portion of said pin proper I5. The free end of leg: portion [Bisformed into loop H which encompasses loop II. at the outer portion of the periphery of the latter. Leg portion [6 of pin I5 maintains. the operative portion of the pin in a spacedzrelationwith the plane of said guard bars I0, but in a central. relation therewith.

Pin proper l5 isso formed as to normally flex,

by its free sharp end l8, towards arms l2 and hooks it. When pin proper- 15 has been pierced through a fabric material, with which the safety pin was tobe engaged, manual pressure upon guard bars lil will open hooks l3 and their tongues. M, the position shown in Fig. 5, causing the free sharp end IBof pin !5' to spring automatically-toWards-arm's f2 and within the space defined'by the spread hooks I3, to be engaged by the latter when the manual pressure at guard barsilflzisreleased and said guard bars [0 spring away fromeach other due to the action of loop i-l. When said-hookslishift towards each other, the same embrace. sharpfree end 18 of pin l5 and maintain the same enclosed and guarded fcrpreventing accidental tearing of clothes or injury; to a person.

When said hooksl3 are in a closed position andinanembracing relation with saidfree end l-.8 10f pin properv l5 tongues M are in a longitudinalxpositionwith relation to each other and with.

relation to pin proper l5, as is clearly seen in Fig. 1. Said. tongues [4 being flat present a smooth surface preventing tear or injury. The upper ends of said hooks l3 and tongues I4 are in a spaced relation longitudinally of the pin so that the same shift without interference from each other during their shifting movement into engagement with pin [5 or out of engagement therefrom.

Arms 12, being in a spaced relation with the plane of guard bars [0, coact with leg portion 16 for the purpose of maintaining both ends of pin proper [5 in a spaced relation with the plane of guard bars l0, thereby permitting pin proper I5 to pierce and engage fabric material of substantial thickness. Of course, when hooks 13 are opened manual pressure from the direction of the plane of said guard bars should be exerted upon pin proper 15 in order to fiex the same away from arms [2 so as to free it completely from hooks 13 in order that pin may be driven by its free end 18 into fabric material. In fact, pin proper may be angularly shifted completely out of the path of hooks l3 by manual pressure thereat to bring the free end 18 of pin l5 above the plane of tongues 14 during the process of driving the pin into a fabric material. Once said pin i5 is engaged with a fabric material, hooks l3 are then shifted away from each other by pressing guard bars 10 toward each other, and when said hooks 13 are brought to an open position the free end of the pin will automatically spring towards arms I 2. The flattened condition of tongues l4 facilitate their sliding below pin [5 preparatory to shifting thereof in the opposite directions for opening hooks l3 and preparatory to the reception of the pin therewithin.

While there is described herein a preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

What I claim as new is:

l. A safety pin comprising a pair of guard bars, a loop integrally formed at one of the ends of each of said guard bars normally urging said guard bars away from each other, a pin member having an offset end affixed to said loop with the pin in a spaced relation with the plane of said guard bars and centrally thereof in position to be flexed toward said plane, arm's integrally formed with the opposite ends of said guard bars and arranged in crossed relation, the free ends of said arms being spaced from the plane of said guard bars in the direction of said pin, and hooks integrally formed with the free ends of said arms and having open sides in opposed relation, when said guard bars are manually pressed toward each other against the tension of said loop said hooks shifting away from each other for receiving the free end of said pin member, the free end of said pin member being flexed toward said arms for automatically entering the space defined by said hooks when the latter remain in an open position, when the pressure upon said guard bars is released said hooks shifting toward each other for enclosing therewithin the free end of said pin member.
